Package: mount Version: 2.25.2-6 Severity: important Dear Maintainer,
-- System Information: Debian Release: 8.4 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.16.7-ckt9-5 (SMP w/4 CPU cores) Locale: LANG=, LC_CTYPE= (charmap=ANSI_X3.4-1968) Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) Versions of packages mount depends on: ii libc6 2.19-18+deb8u4 ii libmount1 2.25.2-6 ii libselinux1 2.3-2 ii libsmartcols1 2.25.2-6 mount recommends no packages. Versions of packages mount suggests: pn nfs-common <none> -- no debconf information "mount /dvd" crashes, with the following line in /etc/fstab /dev/sr0 /dvd udf,iso9660 user,noauto 0 0 where /dev/sr0 is a cd/dvd drive. A command of the form "mount /dev/sr0 /mnt" works O.K. Debug output to /var/log/kernlog follows, see below... After the mount error exit, an attempt to "mount /dev/sr0 /mnt" fails with "/dev/sr0 already mounted" message. A "umount /dev/sr0" fails with "/dev/sr0 not mounted" message. The sr0 device is now unreachable/unusable until after a system reboot. kernlog (relevant lines) >>> May 9 11:40:51 gene64 vmunix: [326817.943679] BUG: unable to handle kernel paging request at 00000000ffffffff May 9 11:40:51 gene64 vmunix: [326817.943785] IP: [<ffffffffa08619b0>] udf_get_last_session+0x0/0x40 [udf] May 9 11:40:51 gene64 vmunix: [326817.943860] PGD c01ef067 PUD 0 May 9 11:40:51 gene64 vmunix: [326817.943958] Oops: 0002 [#1] SMP May 9 11:40:51 gene64 vmunix: [326817.944055] Modules linked in: udf nvidia_uvm(PO) cp210x usbserial joydev nvidia(PO) ohci_pci ohci_hcd May 9 11:40:51 gene64 vmunix: [326817.944373] CPU: 2 PID: 16969 Comm: mount Tainted: P O 3.16.7-ckt9-5 #5 May 9 11:40:51 gene64 vmunix: [326817.944423] Hardware name: BIOSTAR Group TA970/TA970, BIOS 4.6.4 01/14/2013 May 9 11:40:51 gene64 vmunix: [326817.944465] task: ffff8802250e1890 ti: ffff8800c0120000 task.ti: ffff8800c0120000 May 9 11:40:51 gene64 vmunix: [326817.944515] RIP: 0010:[<ffffffffa08619b0>] [<ffffffffa08619b0>] udf_get_last_session+0x0/0x40 [udf] May 9 11:40:51 gene64 vmunix: [326817.944596] RSP: 0018:ffff8800c0123d70 EFLAGS: 00010246 May 9 11:40:51 gene64 vmunix: [326817.944637] RAX: 00000000ffffffff RBX: ffff8801e97a0580 RCX: 0000000000000428 May 9 11:40:51 gene64 vmunix: [326817.944686] RDX: 000000000000ffff RSI: 0000000000000000 RDI: ffff880209cc2000 May 9 11:40:51 gene64 vmunix: [326817.944735] RBP: ffff880209cc2000 R08: 00000000ffffffff R09: ffff8801e97a0580 May 9 11:40:51 gene64 vmunix: [326817.944784] R10: 0000000000005540 R11: 00000000000001ea R12: 0000000000000000 May 9 11:40:51 gene64 vmunix: [326817.944833] R13: 0000000000000001 R14: ffffffffa0867e50 R15: ffff880226049a40 May 9 11:40:51 gene64 vmunix: [326817.944882] FS: 00007f65bf9a6840(0000) GS:ffff88022ed00000(0000) knlGS:00000000f7707740 May 9 11:40:51 gene64 vmunix: [326817.944931] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b May 9 11:40:51 gene64 vmunix: [326817.944972] CR2: 00000000ffffffff CR3: 0000000016fab000 CR4: 00000000000407a0 May 9 11:40:51 gene64 vmunix: [326817.945021] Stack: May 9 11:40:51 gene64 vmunix: [326817.945059] ffffffffa0868238 ffff880226049b08 ffffffffa0867e50 ffff880226049a40 May 9 11:40:51 gene64 vmunix: [326817.945226] ffffffff811c95e9 ffff88020000ffff ffff8800c0123df0 ffff8800c0123d00 May 9 11:40:51 gene64 vmunix: [326817.945396] 00000000ffffffff ffffffff00000000 ffffffff0000ffff 00000428ffffffff May 9 11:40:51 gene64 vmunix: [326817.945563] Call Trace: May 9 11:40:51 gene64 vmunix: [326817.945605] [<ffffffffa0868238>] ? udf_fill_super+0x3e8/0x630 [udf] May 9 11:40:51 gene64 vmunix: [326817.945648] [<ffffffffa0867e50>] ? udf_load_vrs+0x3c0/0x3c0 [udf] May 9 11:40:51 gene64 vmunix: [326817.945692] [<ffffffff811c95e9>] ? snprintf+0x39/0x40 May 9 11:40:51 gene64 vmunix: [326817.945735] [<ffffffffa0867e50>] ? udf_load_vrs+0x3c0/0x3c0 [udf] May 9 11:40:51 gene64 vmunix: [326817.945778] [<ffffffff810eb2c9>] ? mount_bdev+0x1a9/0x1e0 May 9 11:40:51 gene64 vmunix: [326817.945820] [<ffffffff810ebafc>] ? mount_fs+0xc/0xc0 May 9 11:40:51 gene64 vmunix: [326817.945863] [<ffffffff8110557d>] ? vfs_kern_mount+0x5d/0x110 May 9 11:40:51 gene64 vmunix: [326817.945905] [<ffffffff81107e6f>] ? do_mount+0x1df/0xab0 May 9 11:40:51 gene64 vmunix: [326817.945947] [<ffffffff810bcac3>] ? memdup_user+0x33/0x60 May 9 11:40:51 gene64 vmunix: [326817.945989] [<ffffffff81108a5b>] ?
